YINVENTOR. W Koonzz Patented Mar. 8, 1949 UNITED STATES PATENT OFFICE 4Claims.

This invention relates to a device for supporting articles such as knifeblades, spatulas and the like.

It is the object of the invention to provide a simple, light, andinexpensive device in which such articles may be rigidly and permanentlymounted. To this end, the invention consists in the combinationshereinafter described in detail and a preferred form of the invention isillustrated in the accompanying drawings, of which:

Fig. l is a side view of a device embodying the invention;

Fig. 2 is a corresponding view with a portion of the device broken away;

Fig. 3 is a side view taken at right angles to the view of Fig, 1;

Fig. 4 is like Fig. 3 but with a portion thereof broken away in order toexpose the interior construction thereof; and

Fig. 5 is an end view of the device.

A certain type of blade holder is found on the market at the presenttime and has become quite popular. It consists of a steel handle, theend of which is slotted to receive the blade of a knife or the like, andthis blade is rigidly secured in the slot by means of a spot weldingoperation. The objection to this type of holder is its weight, and whenit is considered that such devices are used by engravers and othersperforming very delicate operations it is readily appreciated that suchheavy handles are undesirable.

Such objection may be overcome by utilizing a handle made from suitablelight material, such as an aluminum alloy or some type of magnesiumalloy, but because such handles do not lend themselves to spot weldingoperations, it becomes necessar to find other means of fastening theblade therein, and such means will now be described.

The device of the invention illustrated in the drawings comprises ahandle I, in one end of which is formed a cylindrical recess '2, of asize to receive a pair of semi-cylindrical clamping members 3, 4,between which the blade 5 is placed, whereupon these members togetherwith the blade are driven into the recess of the handle.

The inner ends of these members, 6, l, are shown slightly tapered inorder to facilitate insertion of the members and the blade into thehandle. When the parts are in this manner driven into the handle, it isfound that the blade becomes rigidly anchored therein and will notbecome loose or separated therefrom. The ends of the members shouldextend beyond the end of the handle, as shown, in order to stiffen theblade at this point and may project further than shown if preferred.

It is noticed that the shank 8 of the blade is somewhat reduced in widththereby to provide shoulders 9, [0 which, when the parts are driven intothe handle, lodge within a slot H in the end thereof. When the blade isin this manner guided within the slot l I, it is found that it is notpossible to twist the clamping members 6, 1 within the recess of thehandle and the blade is held so rigidly imposition that it willwithstand any pressure tending to dislodge it.

From the foregoing, it is seen that I have provided a simple andinexpensive device capable of supporting articles such as above referredto over long periods of time without danger of such articles becomingloosened or dislodged.

I claim:

1. A blade holder consisting of an elongated handle having a cylindricalrecess in one end thereof, in combination with a pair of semicylindricalclamping members, and a blade mountable between said members, themembers together with said blade being insertable into the recess in theend of the handle and driven into the recess to lock the blade firmly inposition.

2. A blade holder comprising a handle having a cylindrical recess in oneend thereof and a transverse slot at the entrance to said recess, incombination with a pair of cylindrical clamping members, and a blade,said blade having a shouldered shank of a width to fill the spacebetween the said two members, the members together with the blade beinginsertable into said recess and driven into the recess until theshoulder formed between the shank of said blade and the blade properbecomes lodged within said transverse slot.

3. A blade holder comprising, a handle having a cylindrical recess inone end thereof and a transverse slot at the entrance to said recess,

in combination with a pair of cylindrical clamp.

ing members, and a blade, said blade having a shouldered shank of awidth to fill the space between the said two members, the memberstogether with the blade being insertable into said recess and driveninto the recess until the shoulder formed between the shank of saidblade and the blade proper becomes lodged within said transverse slot,the inner ends of said members being slightly tapered in order tofacilitate insertion thereof into the handle.

4. A blade holder comprising a handle recessed at one end thereof, apair of semi-cylindrical clamping members, and a blade held between saidmembers to be driven with the members into said recess, the membersprojecting beyond the end of the handle in order to stiffen the blade atthis point.
